Abstract

Data from bottom-trawl surveys in the Labrador-Newfoundland area during 1978-80 were used to describe the distribution and abundance and the size composition of Arctic eel pout Lycodes reticulatus, Esmark's eelpout L. esmarki, and Vahl's eelpout L. vahlii. The Arctic eelpout was the most abundant of the three species, occurring mainly in depths of 300 m at temperatures from -0.9° to 3.5 0C. Esmark's eelpout occurred over wide ranges of depth and temperature but seemed to prefer depths of 251-300 m at temperatures from 2.6° to 3.5°C. Vahl's eel pout was prevalent in depths of 201-600 m at temperatures from 2.1° to 4.5°C. All three species were more prevalent off southern Labrador and eastern Newfoundland than on the Grand Bank. Length frequencies of samples from different parts of the area indicated increasing size from north to south for Arctic eelpout but no significant differences in average length for Esmark's and Vahl's eelpouts.
